One of the most common causes of filtration problems is placing the filter paper on the bottom of the filter pan rather than over the filter screen.
CAUTION
Ensure that filter screen is in place prior to filter paper placement and filter pump operation. Improper screen placement is the primary cause of filtration system malfunction.
Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of the filter paper, and ensure that the correct size is being used. While you are checking the filter paper, verify that the
If the pump motor overheats, the thermal overload will trip and the motor will not start until it is reset. If the pump motor does not start, press the red reset switch (button) located on the rear of the motor at the front of the fryer.
If the pump starts after resetting the thermal overload switch, then something is causing the motor to overheat. A major cause of overheating is when several frypots are filtered sequentially, overheating the pump and motor. Allow the pump motor to cool at least 30 minutes before resuming operation. Pump overheating can be caused by:
•Solidified shortening in the pan or filter lines, or
•Attempting to filter unheated oil (cold oil is more viscous, overloading the pump motor and causing it to overheat).
If the motor runs but the pump does not return oil, there is a blockage in the pump. Incorrectly sized or installed paper/pads will allow food particles and sediment to pass
through the filter pan and into the pump. Sediment Particle When sediment enters the pump, the gears
bind, causing the motor to overload, again tripping the thermal overload. Shortening that has solidified in the pump will also cause it to seize, with the same result.
A pump seized by debris or hard shortening can usually be freed by manually moving the gears with a screwdriver or other instrument.
